To all whom it may concern Be it known that i, yEMANtucr. Autunno, a citizen of the United States, residui et Brooklyn, in the county oi Kings and citate of New York, have invented new .and useful Improvements in Mechanical l'i-iorns, of which the followin is e specification.

My invention re etes to e warning epperetus for use on automobiles, motorcycles Amain cylindrical casing, made preter-l ably 0i sheet `steel drewnto shape, is provided with a flange 6 at right engleslthereto co-acting with a front plete f2', to which e. resonator 8 may he secured, to clamp end to hold in place a steel diaphragm 9. find it ,very desirable to providesJ ilexihle projectionl 10, riveted on the diaphragm `neer its center, so that it may hend when the power applied ,at its tip 4is greater then the 'elastic limit ,oi the diaphragm; i iind in practice that this arrangement eliminates the frequent adjustments required in devices of this class. A frame carrying the die lphragm actuating tmechamism is composed of two horizontal posts 14 and his", held in elinement by e `circular front yplete15which its the casing '5, and is adapted to slide therein, endet the rear by e cross-member #13. AQpinion'QB, solid with the rotary shaft 23 is journeled .on said posts; rigidiy mounted on pinion 23 is the bar25, carrying a pewl 26, which drives a ratchet 27 iestencd to :t sleeve l'loo'sely mounted on the pinion shaft 23': 'Un sleeve 3l is loosely mounted .the diaphragm actuating' ratchet 24-, and e springhox is secured on one side ci said ratchet; the spring 36, one end of which is secured to the sleeve '3-1 iscdapted totronsmit ower through the spring hor: to the diep regni actuating ratchet. y

it will he seen that' while the pew 26 is ,drivingfthe l sleeve 31, the spring 35 will re -silicntly transmit ,c rotary Vmotion to the ratchet-Q4 which rapid vibration.

ri spiit lratchet 32, is removably secured at the opposite end oi? the sleeve y31, end e spring pewl 33 is v4adapted to engage said rotchet'BZ and to prevent heck motion of the sleeve when the pcwi ,2G returns -to-'its normal position idly riding on `the ratchet 2'?. The spring" 'is lheld in place by a 'member 34 loosely mounted on post 11d", so that the two portions of the spring 33, one which is in engagement -withthe ratchet 32, sind the otherportion which is flonger 'than will set the digtphrorgm into the portion which engages the ratchetehuts against the shaft l13,rney co-oct=to produce the required elasticity for the shorter end thereof, an eiiect that wouid Vnot have been secured if the longer end oithespring were not flexible and 'did not coact Vwith lthe smaller end, through the rocking post 34.

forward and backward motion een he imparted, hy the operator, to the pinion 23 hyuneans of e rec'iprocartory rock, or preferably `hy e itoothed sector 'i8 mounted on yshaft 16, and adopted to he oscillated there hy. lifiand or [toot power may ,he applied to the sector 'hyfnieens of a handle 34", on the outer side oi the Acosine; 5, or hy means of' e cord ffii secured hy means ci a. screw 22, on zt grooved sector'lf? mounted' on the shaft "L6, und parallel to the sector-i8. i iind that with this ,arrangement, when the driver cannot Ause 'his hund power, he cunoperate on u4 ,foot leverwhich pulls the cord 2l.

The rear part oi the casing 5'is perforated et two .des leaving' c cross-piece 12 carrying e screw 3), in engogement with the 'frame cross-piece 13, end coecting therewith for adjusting thev whole mechanism ,carrying ironie toward and from the diaphragm.

Seid screw 30 is 'termed ci? two portions having diderent threads, one smaller the other larger, ,so that one portion moves quicker than the other, such screw being called ,differential in mechanics. ri`he Inet-al on the side ci the cross-piece 'l2 maybe hent inwardly as shown et il. so that e guide is provided for the ends ot' the cross-piece i3 to iit and to ,slide-therein.

An loval openinc 38 is provided in the casing '5 for the shart 15, which is moved b ack 0r forth in the\ adjustment of the device; theend of the cross bar 13 is provided' with an extension 38, through which the shaft 16 is adapted to pass, while said extension is adapted to close at all times the oval hole 38,`sothat the mechanism may be at all times inclosed from the weather.

Modifications may be made in the means provided in the casing itself for holding 1n place the cross-bars; and many other changes ma be made in the device, as the elimination of the handle 34', and the securing of the grooved sector 17to which the cord'is secured, at the place of the handle.

A pin 2O is fastened to post 14, and engages the inner sides of the oscillating sectors 1 and 18, acting as a stop therefor: the spring '19 is used to return the sectors to ,normal position.

By those skilled in the art many changes and substitutions may be made in the device without departing lfrom the scope of` my claims.
